GROUND ANCHOR.

This invention relates to a new and usefulimprovement in ground anchors such as are employed in connection with rods to which guyropes, cables, etc., may be connected.

In using ground anchors of the type herein contem lated, anopening, such as indicatedr at in the drawing, .is preferably formed in the ground by a posthole digger or other implement and at an angle to the horizontal, as shown. The guy rod B is then driven through the ground so that its inner lthreaded en projects into the oening A,

as shown in Figure 1, after which t e ground anchor is engaged with the threadedend of the guy rod and said guy rod turned so as to seat its threaded end into the anchor. The guy rod B may have an eye C formed on its outer end, or said eye may be detachably secured to the outer end and to which intended to be secured the end `of the cable or rope to be anchored.

In the drawings, 1 indicates the body portion of the ground anchor which is preferably formed with an uppr convex surface, above which extend ri 2, the height of said ribs increasin towards the center of the anchor where t ey are conjoined to the ribs 3 and 4, which with the web wall `5i form a box-like structure having a recess or slot 6 in the shelf-like wall thereof.

7 lindicates a pivot pin assing through this box-like structure, on w ich are pivotal- 1y mounted 'aws 8, said jaws having flaring walls 9 at t eir outer ends and registering semi-cylindrical threaded openings 10 in their adacent faces with which re isters a threade opening 11 in the body wa of the anchor, as sh own in Figures 3 and 4.

1922. serial No. 556,276.

The underside of the anchor is preferably formed wlth diagonally arranged reinforcing ribs 12 which are conjoined to the centrally located boss 13, in which the threaded opening 11, before referred to, is arranged.

One end of the body web of the anchor is provided. with a perforation 15 and a notch 16. 17 indicates an implement, preferably in the form of an elongated metal rod having one end 18 flattened to form a tamping tool,

while its outer end is provided with a cap' l cated, a ground anc or is fitted on the end of the rod 17V and introduced into'the opening A, the operator forcing the anchor upon the end of the rod until the threaded ortion of the rod is forced between the jaws which are ieldingly held together by a spring 23, etailed in Figure 2b and= the threads onthe rod engage the semicylindrical registering openings in the sprin -held jaws. When such engagement is eiicted, the rod 17 is disengaged from the round anchor. The convergingribs 2 will elp in guiding the end of the rod B in between the Laws and into the recess formed by the overan n shelf.

-S ou dthe ground anchor not be connected to the rod, a hook 22 on the underside of the cap on rod 17, can be employed to engage the tzgening 15 in the ground anchor and with aw it from the hole to be again arranged in position on the placin rod for.

engagement with the guy rod. e ground anchor having been engaged between the jaws, the guy rod is now rotated so as to force its threaded end beyond the jaws and intothe threaded opening in the body web of the anchor thus fixing the anchor on the end of the ro When the anchor is so fixed, the earth is replaced in the opening A and preferably tamped by the widened end 18 of the placin rod.

f at an time, it is desired to remove the guy ro it may be unscrewed and withdrawn, and the anchor may ne left in the ground, or may be dug up, if desired.

The boxlike structure which houses in the movable jaws and -their spring, serves to 5 protect'these moving parts from the entrance of dirt or other foreign particles which might interfere with their operation at the time 'that the ground anchor is being introduced into position on the guy rod.

10 After the guy rod is engaged with the movable jaws, then dirt packed behind said jaws and 1n the space between the jaws and the housing serves to hold said jaws fixed, and, hence, is not objectionable.

en the rod is screwed into the anchor, it passes from engagement with the threads of the movable jaws to the threads of the boss of the anchor plate, and hence has a solid threaded engagement with said plate. It is 2Q obvious that the rod may be unscrewed from the plate at any time even though the anchor plate er se be abandoned.

What I c aim is:

1. A ground anchor having a box-like projection extending from its upper side, and which is open at one end, and yielding guy rod attaching means housed within said x-like extension.

f 2. In a ground anchor, a guy rod, a body,

a pivoted set of jaws mounted thereon for engagement with said guy rod, and means yieldmgly holding said 'jaws in operative position.

3. A ground anchor comprising a body portion, and a air of spring-held pivoted jaws mounted t ereon and adapted to engage a guy rod.

4. A ground anchor com rising a body portion convex on its upper we and having converging reinforcing ribs for guiding a guy ro into a predetermined position, and

flexible means on the ground anchor for receiving said guy rod and adapted to hold the same in said predetermined position.

5. A ground anchor comprising a body portion having a box-like housing on its upper side, a pair of spring-held jaws arranged in said housing for engagement with a y rod, the contiguous faces of said jaws being provided with registering threaded semi-cylindrical recesses, and said body portion being provided with a threaded opening in alignment with a recess between said jaws.

6. In combination, a ground anchor, the body of which is provided with a threaded opening, a threaded guy rod, means for guiding said rod to a desired position over said opening when the rod is moved transversely of the opening, said means also serving to hold said rod when so positioned.

7. In combination, a ground anchor comprising an anchor plate having a threaded opening, a guy rod adapted for threaded engagement with and disengagement from said anchor plate, and threaded yielding means for guiding-said guy rod and holding it in position to engage said threaded opening.

8. A ground anchor comprising a rod having threads on an end thereof, a plate having an opening therein, threaded means associated with said plate and adapted to engage with the threads on said rod, said plate being adapted to be positioned in an opening in the earth and said rod being driven through undisturbed earth at an angle to meet said plate whereby said plate may be drawn lup against undisturbed earth in said opening.

In testimony whereof I hereunto aiiix my signature this 10th day rof April, 1922.
